The structure and working principle of liquid ring vacuum pump is analysed

liquid ring vacuum pump is mounted eccentrically in the pump shell more rotor blades. When it rotates, it to the pump casing injection liquid, and the formation and the liquid ring pump casing concentric. Liquid ring and the rotor blade with periodic volume change the rotation of the vacuum pump variable volume.

liquid ring vacuum pump is a kind of interior offset by pump impeller rotation to periodically change studio volume in order to realize the suction vacuum water pump. The studio consists of rotating liquid ring and the impeller, its structure and working principle are similar to those of liquid ring compressor. The following 3 d animation more intuitive:

when the working fluid is water, it is called the water ring vacuum pump. Water ring vacuum pump is a kind of coarse vacuum pump, may obtain 2000 ~ 4000 mpa and the limit of vacuum and a range of 270 ~ 670 air ejector.

when the impeller rotates clockwise in the picture, the water is the impeller. Due to the centrifugal force, water according to the shape of the pump chamber to form a closed loop with roughly equal thickness. The inner surface of the lower part of water ring coincided with the impeller wheel tangent, the inner surface of the upper water ring coincided with the top blade contact ( In fact, the blade has certain insertion depth in water ring) 。 At this point, the impeller wheel and crescent formed between water ring space, the space is the impeller small cavity is divided into several equal number and leaf. If the lower part of impeller as a starting point, when the impeller rotating 180 degrees before the volume of small changes from small to big, small room with the suction connected on the face, at this time in gas, after the suction, chamber from the inlet; When the impeller to rotate, from large to small small room, cause the gas is compressed; When small room and vent connected, gas from the eduction in pump.
